Quantum computation has attracted much attention and investment lately through its theoretical potential to speed up some important computations as compared to classical Turing computation. The most well-known and widely-studied form of quantum computation is the (standard) model of quantum circuits [1] which comprise several unitary quantum gates (belonging to a set of universal gates), arrang...

From February 2010 to February 2011 PM10 aerosol samples were simultaneously taken every 4th day at 7 monitoring sites in Flanders, Belgium. Two of the sites (i.e., Borgerhout and Gent) were urban background sites; one (i.e., Mechelen) a suburban background site, and the other four (i.e., Hamme, Lier, Retie, and Houtem) rural background sites, whereby Hamme and Lier were expected to be particul...

ion. Such abstraction has played an important role in Yemen's modern socioeconomic development, but is unsustainable and now threatens the country's very existence. I develop the argument in three sections. First, I argue that prior to the advent of large-scale groundwater abstraction, Yemen had over several centuries developed a set of indigenous technologies, political and social arrangements...

Cry j 1 is a causative substance of Japanese cedar pollinosis, and it may deteriorate by Cry j 1 invasion to a lower respiratory tract. We observed airborne particles containing Cry j 1 by an immunofluorescence technique using a fluorescence microscope, and we clarified that Cry j 1 exist as aggregates of airborne fine particles (< 1.1 μm) in the urban atmosphere. Airborne Cry j 1 may react wit...

We describe the analytic center cutting plane method and its relationship to classical methods of nondi erentiable optimization and column generation. Implementation issues are also discussed, and current applications listed. Keywords Projective Algorithm, Analytic Center, Cutting Plane Method. This work has been completed with support from the Fonds National Suisse de la Recherche Scienti que,...
